Nocturnal polyuria is one of the main pathogenic mechanisms of enuresis. Disturbance of circadian rhythm of antidiuretic hormone (ADH or AVP), hypercalciuria, and/or solute diuresis are considered to cause nocturnal polyuria, which in turn causes enuresis in patients with relatively small bladder capacity and high threshold for awakening. Evaluation of these factors would guide the therapeutic approach for enuresis.

The present experiment was designed to investigate renal function in conscious rabbits. Pentobarbital caused some reduction of urinary volume and hemohynamics, but the changes were not significant. UnaV, UkV, UclV were not changed by pentobarbital in dose of 3.0~9.0mg/kg i.v.. Urinary flow snd UclV were not changed by pentothal sodium, 5.0mg/kg i.v., but the UnaV and UclV increased from 30.61 to 66.19 uEq/min, from 28.29 to 62.91 uEq/min respectively, after pentothal sodium. There was no change in urinary potassium secretion after pentothal sodium. Left renal arterial infusion of pentothal sodium caused small changes in GFR, and clear increments of UnaV and UclV localized in that kidney in the urethane anesthetized rabbit. Natriuretic and chloruretic effect of pentothal sodium were not seen in mannitol diuresis. These data suggest that 1) the effects of pentobarbital and pentothal may not be the sam in conscious rabbit renal function, 2) natriuretic and chloruetic effect by pentothal may be caused by direct inhibition of sodium reabsorption in the distal nephron in the rabbit.

Renal functional changes following relief of obstruction were investigated with a prospective aspect in a series of 15 postoperative patients using standard renal function measurements with emphasis on osmolar and free water clearance. Sequential measurements of free water clearance revealed earlier changes of postoperative renal function than that of standard renal function. The advantage of this measurement was in postoperative patients with adequate amount of urine output or diuresis. It may be helpful to the management of patients with obstructive uropathy and to early prediction of acute renal failure, especially in patients with post-obstructive diuresis.

In this study, effects of the intraventricular and intravenous dimethylphenylpiperazinium (DMPP) on the renal function of rabbits were investigated. Intraventricular DMPP (100 microgram) elicited diuresis following antidiuresis concomitant with the changes in renal blood flow, glomerular filtration rate and urinary excretory amount of electrolytes (Na and K). The changes in urine flow correlated with the changes in renal blood flow, glomerular filtration rate and excretory rates of electrolytes in urine. Intravenous DMPP (50 microgram/kg) did not affect the renal function.

PURPOSE: This is a descriptive study conducted in order to survey sleep patterns and factors responsible for sleep disturbance among adolescent cancer patients after hospital admission. METHODS: The study group included 46 adolescent cancer patients aged 10 to 19 who received admission care in multi-bed hospital rooms from March to June 2016. Data on patterns and quality of sleep, and factors causing sleep disturbance were recorded using the Verran and Snyder-Halpern (VSH) Sleep Scale, the Pittsburgh Sleep Quality Index (PSQI), and a sleep disturbance questionnaire. RESULTS: There was no difference in patterns and quality of sleep prior to and after hospital admission in the study group. However, patients experienced sleep disturbance, as defined by PSQI > 5, both before (5.43) and after (6.30) admission. The most important physical, emotional and environmental factors causing sleep disturbance after admission were nocturnal diuresis, monotony of admission care, and crying of younger patients respectively. CONCLUSION: This study focused on sleep patterns and factors causing sleep disturbance after hospital admission for adolescent cancer patients. Future studies should aim to develop nursing interventions resulting in an environment that improves sleep quality. Additional studies should focus on developing daytime programs to determine the impact of admission care on other quality of life parameters.

Rhabdomyolysis results from acute damage to skeletal muscles caused by various conditions, of which hypokalemia is a recognized but rare example. Although primary aldosteronism may cause severe hypokalemia leading to rhabdomyolysis, the potassium level of such patients can be within the normal range. Hypokalemia is most frequently triggered when these patients are exposed to an additional insult, such as diuretic stress. Similarly, overzealous consumption of ionic beverages with osmotic diuretic effects can cause hypokalemia. Here, we describe a patient with an aldosterone-secreting adrenal adenoma, who presented with acute rhabdomyolysis secondary to severe hypokalemia triggered by consumption of a large volume of ionic beverage for 3 weeks.

To evaluate the relationship between spontancous diuresis and improvement of pulmonary function in respiratory distress syndrome, 15 premature neonates requiring mechanical ventilation for RDS, who admitted in NICU of Wonkwang University Hospital from January 1990 to June 1992, were studied. The results were as follows (results are mean+/-SEM) 1) Mean birth weight of study infants was 1.82+/-0.08Kg, and mean gestational age was 32.80+/-0.54 weeks. 2) The onset of diuresis occured at a mean age of 29.1+/-2.48 hours with maximum diuresis at a mean age of 41.9+/-1.8 hours 3) Mean urine output increased from 2.25+/-0.43ml/Kg/hr at the stage of pre 12 hours-onset of diuresis (p<0.001), then decreased 3.5+/-0.2ml/Kg/hr at the stage of after maximum diuresis (p<0.05). 4) After maximum diuresis, inspired oxygen gradient, peak inflating pressure, peak end expiratory pressure, mean airway pressure, and respiratory rate were decreased significantly (p<0.05), and alveolar-arterial oxygen gradient was decreased more significantly (p<0,01). So, We conclude that the pulmonary function was rapidly improving after maximum diuresis and these changes reflect the general principle used in ventilatory management of infants with RDS.
